🚀 Release: TEESimulator v3.2 (Hotfix)

TEESimulator v3.2 is rolling out today as an hotfix. This release was pushed ahead of schedule because our recent GitHub build artifacts were expiring, and a severe Google Play Services (GMS) log flooding bug was significantly degrading device performance for many users. 📱⚡

⚠️ Important Development Update:

• Detections: Due to time constraints, we haven't patched all the new detections currently in the wild. However, this hotfix does successfully address a few critical detection points. 🛡️
• LSPosed ➡️ Vector: I (JingMatrix) am currently dedicating my efforts to refactoring LSPosed into Vector. Consequently, TEESimulator's development pace will temporarily slow down. Please stay tuned and monitor the commit history to follow along with our progress! 🛠️👀

Here is the changelog for this release:

🔧 Stability & Performance

• 🛑 GMS Log Flooding: Mitigated massive log spam and battery drain (especially noticeable on WearOS or Nearby Share) by safely bypassing list hooks for GMS.
• 💥 Binder Leak Resolved: Squashed a critical strong reference memory leak during binder transaction interception that caused random crashes.

🛡️ Anti-Detection & Emulation

• 🔑 Pre-Existing Key Override: TEESimulator now detects and replaces hardware keys that apps managed to request before the module was installed, ensuring all future operations remain under control.
• 🧩 Accurate module_hash: Completely aligned the APEX module hashing logic with the official Android keystore2 implementation (including direct /apex filesystem scanning and exact ASN.1 DER sorting).
• 📜 Certificate KeyUsage Fix: Dynamically sets X.509 KeyUsage bits based on the actual key purpose to properly adhere to Android HAL specifications (the first contribution of @Enginex0!).
• ⚙️ Core Improvements: Enhanced KeyMint logging (parsing ORIGIN, OS_VERSION, etc.) and fixed Parcel position resets for cleaner internal error handling.
